No subscription. No vendor lock-in. Every AI change is a git commit you can undo, cherry-pick, or audit.
I started using Aider in March 2026 after hitting rate limits on Claude Code's Pro plan for the third time in a week. I was frustrated — I liked the agentic workflow but resented paying $100/month for a tool that locked me to one company's models. Aider promised the opposite: open source (Apache 2.0), any LLM I wanted, pay only for the API tokens I used, and every change committed to git automatically. Six weeks later, across 9 projects (5 Python, 3 TypeScript, 1 Go) and 6 different language models, I've spent $47.30 total in API costs — $7.88 per week, $1.12 per day of active coding.
The TL;DR: Aider is the best value in AI coding tools and the only one that treats git as a first-class citizen rather than an afterthought. But the terminal-only interface and upfront configuration overhead mean it's genuinely not for everyone. If you live in the terminal and want model control, Aider is unmatched. If you want a polished GUI experience, Cursor or Windsurf will make you happier.
The Git-Native Architecture That Changes Everything
Every other AI coding tool treats version control as an afterthought. Cursor has an undo button. Copilot has a diff view. Claude Code will commit if you ask it to. Aider treats git as its core operating system.
